Back to Neutinos, 3.5keV sterlie ones.

In this week phys-ph paper, authors, Emma L. Horner,1, ∗ Francisco Mungia Wulftange,1 Isabella A. Ianora,1 and Chad T. Kishimoto , https://arxiv.org/abs/2306.1653 investigates, a 3.5KeV line from galatic center, which may be due a decaying, 7KeV neutrino. Have a read.
